Patented Septe17, 1929 UNITED STATES JOHN H. 000K, or SALT LAK-n o1mY,lUrAH VALVE-ACTUATING PLATFORM l;

Application filed June 8,

The present invention relates to platforms, constituting valve actuating means, and it is particularly intended for shower baths, so that when the bather stands upon the platform, the supply of water is automatically turned into the nozzle or other distributing means.

In the accompanying drawings:

Figure 1 is a vertical sectional view io through the preferred formr of construction.

Figure 2 is a plan view with parts broken away. n

As shown, a base yis employed in the form of a spider comprising a central hub 3 with l5 four radial arms 4f. These arms are connected at their outer ends to angular upstanding walls 5, forming a three-sided box, the fourth side being open but the Walls having inturned terminal portions 6 at the ends of said open side. The arms l furthermore have upstanding sleeves 7 that are preferably, though not necessarily integral with the arms.

The central hub 3 terminates in an outstanding ilange 8, and bolted at 9 to said iiange is the casing 10 of a valve mechanism.

This valve mechanism is preferably substantially the same asthat disclosed in my copending application, Serial No. 138,548, filed bept. 29, 1926, now Patent No. 1,691,662. It is provided with an internal valve seat 11 against which normally rests a ball valve 12 that is held against the seat by a spring 18. A plunger stem 14, extending through the top of the casing, constitutes actuating means for opening the valve and this plunger stem has an upstanding head or knob 15.

A rectangular platform 16 is located over the base and is provided at its corners with depending sleeves 17 that slidably telescope over the sleeves 7. Bolts 18, located longitudinally within the sleeves, are fixed to the platform by means of nut-s 19 threaded thereon and embracing bridge portions 20 formed in the sleeves 17. yThe lower ends of these bolts have heads 21 slidable in the lower portions of the sleeves 7 and adapted to abut internal flanges 22 formed in said sleeves 7. Coiled springs 23 are located in the sleeves with their lower ends resting on the flanges 22 and their upper ends bearing against the i928. ,serial No. 283,989.

lower nuts 19. yThese springs obviously server to hold the platform in elevated position. The platform is furthermore provided with depending cornery guide pieces 24. engaged in the corners of the box 5 and serving to preventlateral displacement ofthe platform'` and acting as guides. The downward move-kk ment of the platformy may be; determined by itsresting on the'uppe'r edges of the base walls 5, but the extent oft-his downward movementy may be varied. To" this end `collars 25 surround the sleeve 7 and areadjustably fixedfthereto byset screws; 26, These collars may be set at any height desired and as the sleeves 17 will engage the same when f the platform is depressed, the:downward movement of the platform is thus determined. In any event,lit will be evident that Aor-y dinarilythe `platform is ,f supported by the f springs 23, but that when a person rstands thereupon theplatform will be depressed so thaty the knob 15,` will bemoved downwardly, thereby opening'the valve and permitting the free flow of water through the valve casing. It will be understood that the 'Valve' casing is connected by suitable pipes, indicated at 27 to a supply and to the distributing nozzle n of a shower, these pipes extending through the open side of the base box, which side is left open for that purpose.

A wear plate 28 may be secured to the underside of the platform 16 for striking the actuatingknob 15 of the valve and the posi-` tion of this plate may be readily variedby introducing strips between it and the underyso' forth, the combination with a base spider I frame, of a valve mounted on the centrall portion of the frame, a platform located over the frame, and yielding supports for the platform mounted on the outer ends of the spider frame.

2. In mechanism of the character set forth, the combination with a base having an upstanding side Wall having one side open, of a yieldingly supported platform over the base, and a valve operated by said platform and located in the base Within the wall, the open side permitting the passage of pipes connected to said valve.

3. In mechanism of the character set forth, the combination with a base comprising a spider with substantially radial arms, and an upstanding housing Wall connecting the arms of a platform over the base and having depending guides enga-ged with the housing Wall, means for yieldingly supporting the platform, and a valve on the hase operated by the platform on its depression.

4. In mechanism of the character set forth, the combination with a base comprising a spider with substantially radial arms, an upstanding housing Wall Connected to the ends thereof and upstanding sleeves on kthe ends of the spider arms, of a valve mounted on the central portion of the spider, a platform over thek hase having corner guides slid# ably associated with the upstanding housing Wall, and sleeves slidably telescoping the sleeves of the hase, said platform on its depression actuating `the valve, supporting springs for the platform located in the telescoping sleeves, and bolts in the sleeves and carried by the platform for limiting the upward movement of the platform.

In testimony whereof, I afiix my signature.
